Calgary International Airport in Canada is planning to carry out a major expansion project over the next five years in a bid to expand its existing facilities.
The $2.4bn expansion will include the construction of a new 22-aircraft gate wing and a runway, which will be the longest in Canada, according to the vancouversun.com.
Work will also include building a new 1.3-million-square-foot concourse at a cost of $1.3bn to cater for international flights.
The sustainable concourse will reduce its carbon footprint with the presence of geothermal wells for cooling and heating, and will be able to harvest rain water.
The airport's new 4,267m runway is expected to open in 2015.
The expansion project will also include upgrades to existing facilities and a new air traffic control tower south of the main terminal .
